I don’t see your games, I am sure you care about them sincerely, I see the other “polished” titles and I’m familiar with the Roblox funded development that paid for the creation of the more polished games. I can’t pass criticism on games I haven’t played, such as the the ones you listed. Roblox’s strategy sometimes works sometimes doesn’t, so difficult to generalize. Overall there’s a reason we have never heard of a single game on the platform.
Bloxburg feels like the least janky experience. But overall just moving around using virtual joysticks on a phone is really janky.
Another POV is that the overall catalog of games is very large. Many high quality options to go through before playing your first Roblox game. Even on phones, even free to play. With your level of experience you know that of course every kid would have more fun playing something like Clash Royale or something in the Apple Arcade, the issue isn’t that kids are stupid or tolerate crappier stuff like you imply elsewhere, but that you are not allowed to market expressly to them even in platforms like TikTok where there are many kids.
